1. All but one of the following are ways to obtain a changing the magnetic flux through a loop.A. Changing the shape of the loopB. Changing the material of which the loop is made.C. Changing the size of the loopD. Changing the direction of the fieldE. Changing the magnitude of the field2 The induced electro-motive force on a loop creates a current in the loop. This current, in turn, creates a magnetic field. What is the direction of the magnetic field at the center of the loop when you face the loop and the current in it circulates counterclockwise.A. The field points towards you.B. The field points away from you.C. The field circulates clockwise.D. The field circulates counterclockwise.E. The field is zero.
Go for it just make sure the tube is the same dimension of the tire!
I've done it lots of times when I ran spoked wheels.
Yes, but get a WHEEL LINER, a rubber girdle to cover the spokes and prevent chafing
Answer to 1 is B. Imagine flux like flowing water. You have a loop and the water flows through it. If you change the shap or size of the loop, the water flow will be effected. If you change the direction of the water current, it will again be effected ( Perpendicular to your area vector will have no water flowing at all). Chaning the magnitude is like changing the strength of the water current and more water will flow as the current is stronger. How ever chaning the material will not matter at all. Answer 2 ; has to be A or B. The current and magnetic fields are in different planes. I don't remember which rule would it be but check the right hand or the left hand rule. I am sure other yahoo users will confirm the exact Answer for you :-)
